I want to setup one way replication in oracle 10g Database.
Example: There are 2 database in two locations.DB1 and DB2.
DB1 need to get data from DB2 every one hour and update in DB1 database.
i need to set up a central server with all the master tables and two other local database which will hold the updatable materialized view of the master table...the databases must be synchronized with central server..and user will work on the materialized view database...

Make sure that the replication administrator that you enter below does not exist already in any of the nodes that will be part of the DRG to be created now. If the user exists, that user will be dropped and will be created newly.

Enter replication administrator's name : repadmin

We ran a perl script which is using ldapmodify to change the value of one attribute in all records (7 Millions records).That has been done by creating many of LDIF files each of 10,000 records in 26.04, and by mistake this script has ran 3 times in parallel.Currently the replication between both nodes are stuck, and when I query the ods_chg_log on the master node (node1):
SQL> select count(*) from ods_chg_log;
COUNT(*)
----------
6690594
And the number is not decreasing.
And I queried on the asr_chg_log on the master node (node1):

I have a multimaster advance replication environment and we have less than 10 transaction per day...I want to propagate data as soon as possible like sync if I setup the schedule push to propagate transaction every 5 seconds as below
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (5/60*60*24)',
next_date => SYSDATE,
parallelism => 1,
delay_seconds => 10);
END;
/
in other hand ,book(I mean Advance Replication) has written that for simulating continuous push we should setup it as below so it will propagate transaction every 1 minute.
My second question is:I know interval >= 'SYSDATE + (1/144)' means every 10 minutes a job will start and delay_seconds => 1200 means each job remain aware for 20 minutes, but I can't understand the logic?why it can simulate 1 minute propagation?
BEGIN
DBMS_DEFER_SYS.SCHEDULE_PUSH(
destination => 'orc2',
interval => 'SYSDATE + (1/144)',
next_date => SYSDATE,
parallelism => 1,
execution_second >= 1500,
delay_seconds => 1200);
END;
My thrid question is :Which of the above setups is a better solution for my environment?
Suppose I have materialized view A,B,C. Now I have a new materialized view D which is created from A,B,C. Can I put D into same refresh group?
I am not sure whether D will be refreshed first before A,B,C, resulting that D do not get any update If that is the case, the result will be wrong
If we cannot use refresh group to update nested materialized view, what should we do?
I have a form that the user has to enter a time of an event.
The time entered will most likely be in the past and NOT the current time.
What is the best way to set up a form and a database table for time entry only (exclude the date)?
I have tried datetime on the form with format HH12:MM PM and date on the database.
I have also tried the same with a timestamp on the database.
The time always appears to get entered correctly. However, the time is always stored as AM regardless of what is specified by the user.
How to setup the database for automated RMAN backup. like if we want to have a backup exactly at 8:00 PM IST. So how to configure it.

View 1 Replies View RelatedHow I can maintain a replication scheme from a production database and a standby. I was watching the advanced replication methods of Oracle, but what I want is in the evening to run a process and modify the database incrementally and thus leave until the next night.
And the server I want to allocate to the standby database, also implements other processes, so my settings would be:
Production: Oracle Database 11g Linux 5.5
Standby: Windows 2003 Database 11g
Maybe that data is important, let me make clear that what I want is that the database is updated incrementally.
I have a table MYTABLE in database mydb1 duplicated via materialized view and materialized view log and refresh_snapshot commands to a MYTABLE on mydb2 database.

Is it possible ? What's hapend to the materialized view log where I launch a refresh_snapshots on mydb2 ? How is this materialized view log truncated ?
There is a database db1 which has user U1 in in it contains T1 as table.
Likely,
There is also another database db2 which also has a user named U2 containing table T2 in it.

we have four location, four database server separately, we need to synchronize all the servers.
for example. all the server having table parts. if the parts_count column change in server. it should be change all the four servers.
I have a clients who currently implementing an application that using Oracle 10g in 20 distributed location. Each location will have its own database server and locally managed. I plan to create a Disaster Recovery (DR) Centre for this client in centralised location. I plan to setup 20 Application Server but only one database server with 20 instances. My question, can the Dataguard manage the replication between 20 database (with single instances) and single database (with 20 instances? The reason we design such way is to reduce the license cost of Oracle.

View 1 Replies View RelatedThere are 2 databases, database A and database B. Database A is Oracle 11.2.0.2 which runs on linux and Database B is Oracle 11.2.0.2 which runs on windows xp machine. In database A, there are 100's of tables which are being updated every 10 minutes or 15 minutes. For reporting purpose, the developer wants to run report for the tables. But since database A is being updated every now and then, generating reports takes almost 15 to 20 minutes. So the reports can be generated in Database B. Once in a day the database B should have the updated data from database A so that the reports can be generated in database B with less time. What could be the best solution for the database B to have the updated data on daily basis from database A in oracle?
View 3 Replies View RelatedWe have three unix servers with four databases (10gR2) containing "HP Operation Management Unix" (OMU) server messages for monitoring purpose, and we now want to transfer these data to one new database on a new server for reporting purpose.
The message table in each OMU database keeps the message row until it is "Acknowledged" or for maximum fourteen days, then it is moved to an historic table where it stays for another three days. Keeping data for only seventeen days are a performance issue.The new "Reporting database" is intended to hold messages data for the last 90 days.
I wonder which method to use to move/replicate data against the databases? Materialized view using database link, with view on top of the MVs. How to keep rows longer than the master (source) table, avoiding deletion when master row is deleted
Oracle Streams, with local capture and remote apply. How will this influence on the master database performance. There are about 10000 new messages in each OMU database every day. Is it possible having four streams connections against the reporting database ?
Or should I simply use database triggers which fires after insert and update and applies changes to the reporting database using database links ?
We have Oracle Database Link linked to MySQL . We want to force executing remote statement that contains group by on the remote MySQL server and let MySQL do the aggregation instead of Oracle.
We tried also DRIVING_SITE but it doesn't work and the query that was sent to MySQL from Oracle DB Link didn't include GROUP BY and it looks like that the Group by was executed on the local Oracle.
Is there a way for force executing GROUP BY statements on remote DB instead of the local Oracle DB?

View 1 Replies View RelatedI'm looking for solutions to make real time replications from an Oracle 8i database.
For more details :
- we have an existing database with Oracle 8i
- we want to replicate this database: the replicated database will be used by a web application.
- we need the replication to be in real-time (we wish to have the shortest lag)
For the moment i didn't find much information on the web and it seems that replication solutions for the version 8i are quiet limited.
Some more details :
- The responsible want imperatively that the web application work with a replicated database, without interacting directly with the original one.
- An evolution of oracle should be done but within some years so were trying to find a solution rapidly with 8i.
I would like to know the Replication method which is fast and the best approach,we need two schemas to be moved/replicated to a new reporting database.It appears that data is to be flown in one way,do we proceed with Materialized view replication or please clarify about Oracle Streams and Advanced replication. what are the factors to decide the replication method.

I have one 10g database in other country. I want part of their db (selected tables or tablespaces) and import that data to my 10g DB and i want keep to date this data.
I know two ways
1. Data Pump Imp/Emp via FTP, but i can't send only data that have changed (incremental), i must pumping whole selected part of database (i want only new data from their DB, but consistanse with my DB)
2. RMAN etc. or other archivisation tool, i can do incremental achivisation, but can i send files to another instances (my db) and load only that data? Can i do that with SQL*Loader?
For using replication in our production, here i am testing golden gate as replication tool. I tested all scenario in Uni direction ( source to destination). Now have to test replication with DDL support in Bi-Direction. Not getting any Doc for doing replication in Bi-direction( Two Way). If any one has done the same, then please share limitation of replication in Bi-direction through Golden Gate.
